How to Make Creamy Garlic Boursin Scalloped Potatoes with Gruyere Recipe

Step 1: Prepare Your Oven and Dish

Start by preheating your oven to 400°F. This high heat ensures a wonderfully browned top by the end. Grease a 9×13-inch baking dish generously with butter or non-stick spray to keep the potatoes from sticking and help with even cooking.

Step 2: Make the Creamy Garlic Boursin Sauce

In a medium skillet over medium heat, melt 3 tablespoons of butter. Whisk in 1/4 cup of all-purpose flour and cook for about a minute to form your roux—this step is crucial for thickening. Slowly whisk in 1 3/4 cups of milk, followed by 1 cup of vegetable broth, stirring constantly to avoid lumps. Next, add 150 grams of Garlic Boursin cheese, 4 cloves of grated garlic, 1/2 teaspoon dried thyme, 1 teaspoon kosher salt, and 1/2 teaspoon black pepper. Continue whisking for 2 to 3 minutes until your sauce is thick enough to coat the back of a spoon. This creamy sauce is the heart and soul of this recipe, blending savory garlic goodness with herbaceous warmth.

Step 3: Layer the Potatoes and Sauce

Thinly slice 3 pounds of Yukon Gold potatoes (about 1/8 inch thick) and slice 1 Spanish onion. Begin by layering half the potatoes in the baking dish, followed by half the onions, then half of the sauce, and 1/2 cup of grated Gruyere cheese. Repeat this with the remaining potatoes, onions, sauce, and another 1/2 cup of Gruyere for a rich, luscious stack.

Step 4: Bake Covered and Uncovered

Cover the baking dish tightly with foil and bake for 30 minutes. This covered stage helps the potatoes soften thoroughly. After 30 minutes, remove the foil and bake uncovered for an additional 35 to 40 minutes to brown the cheese beautifully and achieve a bubbly, golden crust that’s impossible to resist.

Step 5: Rest and Garnish

Once the potatoes are tender and the cheese is perfectly browned, take them out of the oven and let them sit at room temperature for 20 minutes. This resting time allows the sauce to thicken slightly and the flavors to meld beautifully. Just before serving, sprinkle with finely sliced fresh chives for a pop of color and a subtle oniony freshness.

Garnishes

Beyond fresh chives, consider sprinkling some finely chopped parsley or a light dusting of smoked paprika for a hint of color and flavor contrast. A delicate drizzle of truffle oil can also turn this dish into an elegant treat for special occasions.

Side Dishes

This dish pairs beautifully with roasted or grilled meats like herb-crusted chicken, steak, or pork tenderloin. For a vegetarian meal, serve alongside a crisp green salad or sautéed garlic green beans to balance the richness of the scalloped potatoes.

Creative Ways to Present

Try serving the scalloped potatoes in individual ramekins for a personal touch at dinner parties. Alternatively, layer thin potatoes in a decorative spiral to impress guests visually before baking. You can even add caramelized onions between layers for an extra sweet and savory surprise.

Make Ahead and Storage

Storing Leftovers

Leftover Creamy Garlic Boursin Scalloped Potatoes with Gruyere Recipe keeps wonderfully in the refrigerator for up to 3 days. Store them in an airtight container to preserve moisture and flavor, then reheat gently to avoid drying out.

Freezing

You can freeze this scalloped potato dish if you want to prepare in advance. Cool completely, then cover tightly with foil or plastic wrap and a layer of freezer-safe wrap before placing in the freezer. For best taste, consume within 2 months and thaw overnight in the fridge before reheating.

Reheating

Reheat leftovers in a 350°F oven covered with foil for 20–30 minutes until warmed through. To revive the crispy cheese topping, remove the foil for the last 5 to 10 minutes of reheating. Avoid microwaving, which tends to make the potatoes rubbery or soggy.

FAQs

Can I use a different type of potato?

Yukon Gold potatoes are ideal due to their buttery flavor and creamy texture, but you can also use red potatoes or russets. Just note that russets might absorb more liquid and become softer.

Is there a substitute for Garlic Boursin cheese?

If you can’t find Boursin, try mixing cream cheese with garlic and herbs for a similar effect, or use a soft herb-flavored goat cheese. The key is having a creamy, garlicky component to the sauce.

Can I make this recipe dairy-free?

This recipe relies on cheese and dairy for its signature creamy richness, but you could experiment with plant-based milk, dairy-free cream cheese, and vegan cheese. The flavor and texture will change, but it can still be delicious!

How thin should I slice the potatoes?

About 1/8 inch thick is perfect. Thin slices cook evenly and allow the sauce to penetrate fully, creating those tender, melt-in-your-mouth layers.

Can this dish be made gluten-free?

Yes! Use a gluten-free flour blend or cornstarch to thicken the sauce instead of all-purpose flour. The rest of the ingredients are naturally gluten-free.
